' To all whom it me concern:

Be it khowiith t'I, CAsT'irRnN J. MARiUs,

" a citizen hi the :UfiitedfSt'at'es of America, and resident-of'west Hoboken, in the county of Hudsonystate' of New Jersey, have invented certaiii new' aiid useful I'mpro'vejm'ents lintisli ping Devices, of which the followin Isa sp c'ificati'on.

time securing the 15 invention has for its object the product1oii'of' an'anti-slipping device having a base plate, pifeferabl 0 sheet metal, so designed as 'to provide a rmand sufficient support for the anti-slipping pads", while at t e same atter against lateral displacement.

Anti slipping devices havin sheetmetal base lates are not new with t is invention,

but- 1 n all de'yices of this character with which I am acquainted, the plat'es heretofore in use have either failed to provide a simple and suffieient-means for supporting the pads a alinst' the pressure of traflie, or have not r iably held them against lateral displacement and loss.

. accomplish the object of my present invention by slitting or cutting the base plate at two or more polnts so removed from each other as to provide an intervening strip of the plate of sufficient strength to serve as the support forthe pad against any ordinary pressure, and stamping or turning the metal up at the slits. The pad being laced on the intervening strip, between t e slits, the turned up ortions of the plate are then pressed agamst the pad to prevent lateral displacement of the latter. 11 order to preclude the possibility of displacement I prefer to make the slits of a curved or irregular design, concaved with respect to each other, whereby upon formation of the turned up portions or wings a partially closed area or pocket is produced which acts to retain the ad against displacement in any direction. may vary this construction to accomplish the same result by forming the pads to fit into the slits made in' the plate and folding or stamping the wings over the edges of the pad asdescribed.

Having set forth the objects and nature oi invention, I will now describe the same in detail, having reference to the accompanyin drawings, in whichigure 1 is a plan view of my device showing the anti -s' ipping pads mounted in a late. Fig. 2 is a similar view of the devil-e before the )ads are inserted therein. F is a detail view in cross-sectional elevation on the line 3+3 of Fig. 1. Fig. 4 is a view in crossse'o'tional elevation along the line 44 of Fig. 2. F i 5 is a detail plan view of the bottom of the ed plate, showing the lines on which the same is out, but showing the retaining win s as yet uniormed. Fig. 6 is a view sim'i ar to Fig. 5, the retaining wings having been ressed upward to receive the pad.

Re errin to the drawings, and particularly to Fig. 5, the base plate (1) is shown as cut or slitted along-lines 2 and 3. These lines are oppositely disposed and somewhat remove from each other to provide an intervening strip (4) which extends between the wings (5) and (6) when the metal is folded or turned up at the slits, as shown in Fig. 6. The cuts, or slits, (2 and 3) are shown in the drawings as curved or concaved toward each other, whereby, upon formation of the win s (5 and 6), a partial inclosure or pocket between the wings is produced.

In practice the wings formed at the slits are forced upwardly, to 90 or more, so that the anti-slipping ads may be set into the pockets. The'pa s being in place, the wings are then turned inward, as by means of a stamp or die, to engage the ads firmly. If, however, the pad is of a flexib e matt a1, such as rubber, or is introduced into the pocket in a molten condition, it is not absolutely necessary to turn the wings into an initial position other than the position they finally assume.

' he strip (6),.between the wings, serves as a baseor support for the pads; and as lateral displacement by the curvature of the wings. In the drawings I have shown the wings as of a simple curve. Any other curve or irregular form of cut-,however,provided it tends to inclosc the pad and. retain it in place, will answer the purpose.

Although I have shown and described my retaining wings as formed by turning the metal at each slit upward and away from the other slit, it is obvious that the wings may be formed byturning the metal at each slit upward and toward the other slit. In the latter instance the intervening supporting stri (6) would have greater width and strengt 1, but on the other hand undesirable holes would be formed in he plate outside of the wings.

In Fig. 1 my preferred arrangement of invention in detail, what I claim and desire strip and retaining wings, an anti-slipping anti-slipping pads and retaining devices is shown. These are arranged in rows, staggered with respect to each other. lnithe g present instance the curved style of wings i shown permits oi the pads fitting closely to each other, whereby a large area of antislipping surfa'ce'is possible and an attractive appearance secured.

Whereas my invention as described is useful in connection with'any character of anti-slipping pad, yet I consider it particularly useful in connection with an antislipping pad of the character set forth in my co-pending application filed Nov. 27,1905, No. 289,301.

-The anti-slipping material of my aforesaid application, which is composed of particles of carborundum or other grittyj material united by metal, is of a nature to i form, in cooperation with the supporting device'ofi great durability and efiiciency.

Having described an embodiment of my to secure by Letters Patent is I 1. In an anti-slipping .device, a sheet metal-bed plate having wings turned upward from the-surface of the plate intermediate the edges thereof, and a strip of the plate intermediate the wings, whereby a ocket with a" supporting base for anti-slipping material is formed, a

2. An anti-slipping device comprising a sheet In ital-bed plate having wings turned upward from the surface of the plate intermediate the edges thereof, a strip of the plate' intermediate the wings and antislipping material held between the wings on the intermediate strlp.

3. In an anti-slipping device a sheet metal bed plate having retaining wings proj ecting upward from its=surface intermedlate its edges and a supporting strip between the Wings.

4. In an anti-slipping device a' sheet metal bed plate havlng wings turned up ward from the surface of the plate inter imediate its ed es and a supporting strip between the wings, the wings being concaved with respect to each other, whereby a pocket with a supporting base for antislipping material is formed.

5. An anti-slipping device comprising a sheet metal bed plate, having wings turned upward from the surface of the plate intermeiliate the edge thereof, a strip of the plate intermediate the wings, and an antifriction material com )osed of particles of grit united by a meta in the pocket on the strip between the Wings. 1
